Application scope of Anhui Yulong New Material Technology Co., Ltd.'s early-strength antifreeze
1. Suitable for industry Precast and cast-in-situ concrete and reinforced concrete for civil construction.
2. Applicable to prestressed reinforced concrete and other reinforced concrete where the use of chloride salt is not allowed
3. Carry out rapid construction under constant mixing conditions.
4. Carry out normal construction under alternating positive and negative temperature natural temperature conditions
5 .Prevent newly poured concrete from early freezing damage at negative temperatures and accelerate strength development.
6. Prepare early-strength concrete with large slump, and mix and pump the concrete on site;
7. Suitable for concrete construction under natural temperature conditions where the temperature is not lower than -15 degrees Celsius. If after the concrete is poured, effective measures can be taken to ensure that the temperature between the surface temperature covering layer and the concrete surface is not lower than -5 degrees Celsius for not less than 7 days, the maximum temperature during construction and maintenance can be used without restrictions. The dosage of JH early-strength antifreeze shall not be less than 8% of the total mass of the cementitious material.
8. It is suitable for preventing freezing damage of all types of mortar.
9. Does not contain harmful ingredients that pollute the environment and affect human health.
Dosage of early-strength antifreeze from Anhui Yulong New Material Technology Co., Ltd.
1 .The dosage of Anhui Yulong New Material Technology Co., Ltd.'s early-strength antifreeze should be based on the maximum temperature during the curing period within the first 7 days after concrete pouring (according to the weather forecast) and the requirements for the concrete strength development speed.
2. When heating raw materials and water during winter construction, if the concrete temperature is high and the dose of JH early-strength antifreeze is large, it should be heated under natural temperature conditions. Conduct samples to find out whether the concrete setting time is compatible with the construction method used to prevent rapid setting, because when the dosage of jh early-strength antifreeze is greater than 5%, the concrete setting time will increase with the increase in dosage and temperature. increase and shorten rapidly.
Introduction to main performance
Positive temperatures require rapid construction projects, and minus 10 degrees Celsius requires strength of 28 Tianda 70% engineering, the greater the dosage, the stronger the coagulation-promoting effect.
